Abstract (en)

[origin: WO2007110483A1] Concluding the validity of an uplink synchronization parameter, such as a timing advance, in a packet-switched radio system. The method includes: detecting (802) an uplink synchronization parameter; measuring (804) an interval from the detection of the uplink synchronization parameter; and comparing (806, 808) the measured interval with a predetermined threshold and, if the measured interval is shorter than the predetermined threshold, concluding (810) that the detected uplink synchronization parameter is still valid, or else concluding (812) that the detected uplink synchronization parameter is no more valid.
